Supported transmission modes

The various transmission types can be selected for every process data project (PDO) in the network management (NMT).

The following transmission types are supported for Rx-PDOs:

Rx PDO transmission mode

Transmission type

Mode

Description

0 – 240

Synchronous

The received data are transmitted to the inverter as soon as the next synchronization message is received.

254, 255

Asynchronous

The received data are transmitted to the inverter without delay.

The following transmission types are supported for Tx PDOs:

Tx PDO transmission mode

Transmission type

Mode

Description

0

Acyclic synchronous

Tx PDO is only transmitted if the process data have changed and a SYNC object was received.

1 – 240

Cyclic synchronous

Tx PDOs are transmitted synchronously and cyclically. The transmission type indicates the number of the SYNC object required for triggering transmission of the Tx PDO.

254

Asynchronous

Tx PDOs are only transmitted when the corresponding Rx PDO has been received.

255

Asynchronous

Tx PDOs are always transmitted as soon as the PDO data has changed.
